For example, the Lie-Poisson bracket \$e(3)\$ includes the Euler-Poinsot model describing motion of a rigid body around a fixed point under gravity and the Kirchhoff model describes the motion of a rigid body in ideal fluid. Advances in computer algebra algorithms, in implementations and hardware, together allow the computation of Hamiltonians with higher degree first integrals providing new results in the search for integrable models. A computer algebra module enabling related computations in a 3-dimensional vector formalism is described.}, language = {en} } @misc{SokolovWolf2004, author = {Sokolov, Vladimir V. and Wolf, Thomas}, title = {Integrable quadratic Hamiltonians on so(4) and so(3,1)}, arxiv = {http://arxiv.org/abs/nlin.SI/0405066}, url = {http://nbn-resolving.de/urn:nbn:de:0297-zib-8085}, number = {04-33}, year = {2004}, abstract = {We investigate a special class of quadratic Hamiltonians on \$so(4)\$ and \$so(3,1)\$ and describe Hamiltonians that have additional polynomial integrals.
